NDSS 2020 - HYPER-CUBE: High-Dimensional Hypervisor Fuzzing

HYPER-CUBE: High-Dimensional Hypervisor Fuzzing Hyper-Cube is a black-box fuzzer designed specifically to test x86 hypervisors Our approach is based on a custom operating system that implements a custom bytecode interpreter to enable fuzzing of emulated hypervisor components The OS is tailored to work with most x86 hypervisors that support either BIOS or 32-bit UEFI boot
